' to provide an improved agricultural ma- Y chine particularly adapted for work in vineposition of their axis tothe speed of travel of travel relatively to yards or other places where cultivated in rows. 4

llt is another object of the invention to provide a machine oit that kind in'which the driving wheels (which with the tilling implementgenerally a rotaryv one-:form the support for the machine) are adapted for such movement relatively to the frame or body of the machine that they can act as a guiding means by changing the angular relatively to the main particular in relathe crops are chine as a. whole, and tion tothe axis of the tilling implement.

lit is another object of the present invention to provide a motor driven agricultural machine in which the driving axle, notwithstanding its power transmission mechanism in connection with `the motor, is resiliently mounted on the vehicle.

llt is a further object of the invention to provide a motor driven agricultural machine having wheels the axis universally about a central point of the said axis between the wheels, thepower being communicated to the wheels from the motor through the said central point.

vIt is ai'urther object ci the present invention to provide an agricultural machine having a motor, a resiliently connected driving and iding axle and a power operated rotary til ing implement in which the Speed the speed of the motor can be varied and in which the speed. of rotation of the tilling implement relativel can be varied..

'llhe machine shown in a spring suspension g the drawings consists essentially of a motor vehicle carrying the tools and or' a ratus proper.

'llhe tool-carrying vehicle comprises a c arriage 40 mounted on wheels 41 and carryingv the motor 42 and clutch device 43.

plowing or tilling appagures are drawn to an 65 tid The motor 42 and the clutch mechanism i 43 are arranged under a hood or bonnet-44. A single gear case 45 which incloses allthe parts for transmitting motion and changing istraversed by the axle 46. first change speed gear 47 within the casing is situated in the front of the gear case aforesaid and regulates the speed of the machine as a whole relativelyto the speed of the motor without changing the speed ratio between the driving wheels and the plow.

A second speed changing gear 48 located at the side vofthe gear case is Aadapted to alter the speed ratio between the driving wheels 41 and the working im lement 58.

The tool 58 is arranged at t e rear of the gear case.` lt comprises two' sections, as

shown in Fig. 5, one with a right-hand screw to throw up or to iS capable of yielding in every direction so These change speed gears can be of any,

Advance. Tool. 30 meters 90 revs. 40 a 90 ce 41 130 A55 130 This represents a workin of the soil which varies from a thin s ice to a wide strip, or, in other terms, from fine pulverization to very coarse granulation.

The axle 46 revolves in bearings 49 and 50 (see Figs. 1, 2 and 9) supported by springs hereinafter referred to and is driven at its center by means of a ball and socket hub 51, shown in section in Fig. 8, which as to allow the wheels to follow all the undulations of the ground without affecting the level position of the apparatus, or, espe-V cially, that of the tools. In addition this arrangement permits of changing the direction of travel Without hindering the working of the tools.

Two vertical springs -52 keep 'the axle parallel to the plane of the apparatus on level ground. One end of each spring is connected to the respective end of a cross bar 62. (Fig. 9) carried upon an adjacent part of the lmachine, and the Vother end of each spring is attached to the bearing 50. On uneven round these springs allow the wheels to fo low the surface without materially changing thepositionof the apparatus in the lateral sense. Two other springs 53, acting horizontally, each attached by its ends to a part of the machine and the bearing 50 respectively maintain the wheels substantially parallel to the carriage. -In order to direct the apparatus on to its work, it is merely necessary to act upon the said -springs by means of handles 54 fixed on the arm pieces 55 and attached to the springs -53 by rods 56. Upon these arm pieces may be fitted controls for the motor and the speed changing mechanisms the clutch control being designated 43. They also allow the operator to elect the engagement or disengagement of the tools with the soil and also to turn the machine if desired. 57 is a slide shoe fitted with a stem 60 for regul'ating the depth of the working and Jfor keeplng thev machine straight. For ridge working this shoe forms a slicer for working the portion of ground situated between the two tools. The upper end of the stem has a spring suspension (S1-firstly for Vpermitting the tools to be engaged with the .3 carried by the curved hub 4, of a gear 5 that is driven from the engine by means included in the change speed gear 47.

-The hub "4 is mounted for vertical rotation in bearings 6 and the inner ends 7 of Athese bearings close the ends of the guides 3 to prevent the escape of the rollers 2. With this construction a universal joint or drive will be provided between the engine and axle. v

Having now described my invention, what I claim as new and desire to secure by Letters Patent is 1. An agricultural machine comprising a motor driven vehicle having a pair of driving wheels, a ball and socket hub at the center of the driving axle thereof through which the driving power is transmitted, spring mountings for the driving axle, a resiliently mounted sliding support for the vehicle, a power operated tilling implement, means for varying the speed of travel and means for var ing the speed of operation of, thev tilling implement.

2. An agricultural machine comprisingr a motor driven vehicle having a pair of driving wheels, a ball and socket hub at the center of the axle thereof through which the driving power is transmitted` vertically acting spring .mountings for the driving axle, a resiliently mounted sllding support for the rear of the vehicle, a rotary tilling implement, means for varying the speed of travel vand means for varying the speed of operation of the rotary tilling implement.

Vsprings for restraining relative rearward movement of the wheels, a pair of manual mamme control levers for moving the Wheels independently backward to steer the machine, a pair of vertically arranged springs to resist relative upward movement of the wheels, a resilient rear support for the machine, a power driven rotary tilling implement, means for varying the speed of travel of the machine, and means for varying the Speed ratio between the driving wheels amel tie tlling implement.

In test1mony whereof ll have signed my name to this specification.
